White to transparent gradient with background image

I need to apply a white to transparent gradient which covers about a 1/4 of the top of the page and a background image visible for the rest of the pa开发者_运维百科ge.

Im looking to achieve a seamless blend from a gradient to a textured image and to do this in CSS3.

I recommend Ultimate CSS Gradient Generator - ColorZilla.com

It's a well designed tool and there's a white to transparent preset.

The CSS code that it generates for a white to transparent gradient is this:

background: -moz-linear-gradient(top, rgba(255,255,255,1) 0%, rgba(255,255,255,0) 100%); /* FF3.6-15 */
background: -webkit-linear-gradient(top, rgba(255,255,255,1) 0%,rgba(255,255,255,0) 100%); /* Chrome10-25,Safari5.1-6 */
background: linear-gradient(to bottom, rgba(255,255,255,1) 0%,rgba(255,255,255,0) 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#00ffffff',GradientType=0 ); /* IE6-9 */

I prefer to use another tool for gradients generation - EnjoyCSS. It also allows to generate other CSS features like background, shadows, transitions etc.
